SYSTEM AND APPARATUS FOR FLUSHING.

SPECIFICATION forming part of Letters Patent No. 761,236, dated May 31 1904.

' Application filed March 2,1903. Serial No, 145,681. (No model.)

To ctZZ whom it may concern:

Be it known that I, J ANG LANDSING, of Rock- Ville Center, county of Nassau, and State of New York, have invented certain new and 'useful Improvements in Systems and Apparatus] for Flushing, of which the followingis a specification, reference being had tothe accompaf nying drawings, forming a part hereof.

This Invention 1s concerned with the provision of a system and means whereby the" service and drainage pipes of a building or .dwelling may be flushed automatically and at predetermined intervals. It is well known that in houses which are closed for any considerable time the water in the service-pipes gather impurity and is rendered stagnant and poisonous therebya condition which when established is not always removed by simply permitting the water to run through said pipes when the house is reopened for occu simple and inexpensive means which may be easily and quickly connected with the piping of the house for permitting the water in the main to flow at regular predetermined in- I tervals through the service-pipes and to be discharged into the drainage-pipes to effect.

the cleansing of the entire piping system of the house automatically for any length of time.

Hitherto means have been devised for effecting automatic flushing in which the operative power is entirely independent of the water in" the main, being furnished by a separate electrical device or clockwork mechanism.

In accordance with the present invention means are provided for effecting'automatic flushing, which means are adapted to be operated by the water in the main.

Another object of the invention is the proval.

vision of a safety device to be employed in this system whereby when one or more wastepipes become clogged the water may be au- 3 ing drawings, in which Figure 1 is a view in vertical section ofa housewith the present system applied to the plumbing therein. Fig. 2 is a similar view, the house being provided with a roof-tank. Figs. 3 and 4 are detail sectional views of the closets and closettanks. Fig. 5 is a plan view of the cellar-tank and its connections with the main. Fig. dis a view, partially in section and partially in side elevation, of the cellar-tank and its connections with the main and the sewer. Fig. 71s a detail view of the safety device. Figs. 8 and 9 are respectively sectional and plan views of one form of closettank with an automatic trip-bucket mounted therein. Figs. 10 and 11 are respectively sectional and plan views of another form of closet-tanks with an automatic trip -bucket A tank a is placed in the cellar of the building in which the present system is to be installed, and said tank is preferably placed near a supply-tube 0, provided with a valve (Z and valve-operating handle 03 for supplying water to the tank from the main and a valve 0 and valve-operating lever a in operative relation with a float f in said tank. The tube c,which empties into tank a, communicates with the main 6 at a point between valve 6 and the service-pipes 1'. Tank (0 is provided with a discharge or'drip cock it in the bottom thereof and opening into a waste-pipe 71/, connected with the main sewer. Through said cook the tank may be emptied, and the time required for a complete discharge of the water in said tank may he graduated to any desired inter- Float f, which rises and falls with the nections between float f and valve 0 sepa-' water in said tank, is connected by a link ito one end of an oscillating bar 7', which is pivoted on the upper edge of the tank, the other end of said bar being operatively connected with valve-operating lever e by a link 70. Arm j is preferably hollow and is provided with a quantity of mercury, whereby the movement of said arm from its horizontal position, which position said arm assumes near the middle of its stroke, is slightly accelerated to assist it over the middle point of its motion, thereby rendering the opening and closing of: valve 0 more sudden than it would otherwise be. In order to render the turning of the water on and off as sudden as possible, said valve 0 is formed with a straight opening 0 therethrough, whiclrin one position of said valve is adapted to register with the openings in the main. Moreover, valve-operatinglever a is so connected with respect to float j that normally or when the tank is filled the opening through said valve is substantially at right angles to the main, and when the float is in its lowermost position, which will occur upon the emptying of said tank, said valve 0 will be opened to its greatest extent, thus permitting a flow of water therethrough to the service-pipes g and also to the tank itself by way of supply-pipe 0. As the tank is again filled float f rises and valve-operating lever e is gradually moved by the connecting-links i and is and the oscillating armj to close valve 0. It will therefore be seen that valve 0 will be turned through a certain angle before reach ing its open position and that it will be opened and closed suddenly. As soon as said valve is closed and the water from the main to the service-pipes g is cut off water will flow down from said service-pipes and through pipe'c into the tank, thus further raising float j, which in turn moves valve-operating lever e. In this way after valve 0 has been closed water will still continue to flow through pipe 0 to raise float f and to move valve 0 to its initial position. It will be understood, however, that inasmuch as the area of the service-pipes Q will differ in different cases it will be necessary to determine the precise eonrately for each particular case. v

The pipes 9 represent the usual servicepipes for conducting water from the main to different parts of the house where it is consumed for various purposes. These pipes 9 will generally terminate either in a faucet Z, which empties into a bowl m, or in a tube emptying into a flushing-tank a. In accordance with the system of flushing to which this invention relates when the house is closed for any considerable time the ends of the service-pipes g are opened and perforated plugs 0 are inserted therein, the perforations in said plugs being of different areas which are inversely proportionate to the force orhead of the water in the ends of the pipes in which they are inserted. In this way the same amount of water will flow out through the ends of each pipe in a given time, although the force or head of the water in each pipes end will vary with the height of that end above the main. In the flushing-tanks a the usual mechanism, which is connected with a float therein for controlling the discharge and filling of said tanks at, is preferably disconnected, and a siphon p is preferably inserted in the discharge-openings of said tanks, the height of which siphon will be determined by the quantity of water which the tank will receive during a single flushing interval. When these few simple connections have been made, the system is completely installed and ready for operation. It only becomes necessary now to regulate the interval between the several flushings and the interval during which each flushing shall take place. The interval between the several flushings is regulated, as stated above, by thedri'p-cockit, so that a complete discharge of'the' tank maybe made to require a period equal to the desired interval. When the dripcock 72. has been set to regulate this interval, which is the interval of complete discharge of tank cnvalve (Z in pipe cmay be set to regulate the interval required for filling the tank, which interval, it will be obvious, is that during which the flushing takes place. It should be observed, however, that while the tank is being filled the water is escaping by drip-cock h, and accordingly it'would be more accurate to say that the interval of flushing is regulated by both valve [Z and cock it rather than by valve (Z alone, although the effect of cock IL upon the interval for filling the tank will in mostcases be negligible. Each discharge of tank a will be followed directly by the flowv of water through the main 6 up through service-pipes g. These service-pipes will discharge into their respective bowls m or flushing-tanks n, and in the latter case the flushing-tanks becoming filled above the tops of their respective siphons 19 will discharge into the closets 9 below. In this way the service and waste pipes are regularly and automatically cleansed by mechanism which is both simple and inexpensive. v

In some cases it'may be preferable to provide a roof tank a, into which the water from the main 6 and valve 0, controlled by tank a, which may also be placed upon the roof, may be directly discharged, and from this rooftank a siphon-discharge pipe is connected with the service-pipes g, as illustrated inFig. 2. Among the cases in which such an arrangement is desirable are those in which the head of the water in the main is either too great or too small or'where it is variable,so that in order to secure a uniform head of water of the proper strength for the purposes'of flushingin themanner 'hereinbefore described some such means should be provided.

" It should -be noted that in some cities there is a large consumption of water at certain times during the day and in many circumstances during the entire day, which consumption so reduces the force of the water in the main that it is not sufficient to cause a flow of water to the upper stories of ahouse. In

such casesa large tank 9", Fig. 12-, similar to tank a, is provided in the topof the house in which the system is to be i'nstalled,.which tank is of such capacity as to provide a quantity of water sufiicient-for flushing during the intervals when the force of the water in the main is reduced. The main 6 will be extended to the roof and near said tank 0, and the same attachments will be made between the main andtank r as were made between the main and cellar-tank 0, already described. The discharge-pipe of tank 1 however, is not provided with a discharge valve and cock,,as in tank a, but Opens freely into pipe 8, which conducts water from tank 0" to tank a in the cellar, pipe is in all respects answering the; purposes of the main in the'fir'st case. Cellari tank a in this case is identical with tank a which has already been described, and the in the main would operate the same and that the cellar-tank a will thereby be regularly filled and discharged and the flushing of the service and draining pipes effected, as has been described hereinbefore.

As was explained above, when the system is installed the mechanism ordinarily controlling the discharge and filling of .the flushing-tanks n is disconnected and siphons p are inserted in the discharge-openings of said tanks. In Figs. 8 to 11, inclusive, additional mechanism is illustrated which, if desired, may be attached to the flushing-tanks n in 0rd er to provide for the proper flushing of these tanks and the closets connected therewith. Such mechanism comprises a trip-bucket n, pivoted upon a rod of and having suitable connections with the usual trip-beam 72 Before describing the operative connections between each trip-bucket and the trip-beamit should be observed that there are in general two forms of closet-tanks, one type of which, as illustrated in Figs. 8 and 9, is provided with a siphondischarge and the other type of which, as illustrated in Figs. 10 and 11, is provided with the ordinary valve-discharge. In either case upon the installation of the system these flushing-tanks are each provided with a trip- It will 1 bucket having secured thereto an arm or rod,

as if, upon the end of which is pivoted a short catch-pin of. Each trip-bucket n is mounted so as to be directly underneath the corresponding'supply-cock n, the floats ordinarily controlling the valve in said supply-cock having been previously disconnected. Each tripbucketn is provided with a small openingn in the bottom thereof, which is normally closed by the end of a curved'rod a, secured to the side of the tank T0. In the case of a tank having a siphondischarge the float therein is connected by suitable chain to the end of the trip-bucket. In thecase of a tank having a simple valve-discharge the float is connected to one'arm of a bell-crank lever 02", pivoted upon a bracket n, the other arm of the bell-crank lever having a notch in which a pin n on the trip-beam may rest while the tank n is being emptied, and a spring n being provided to move said lever upon said pin, at the beginning of the discharge. The dischargeand v filling of these flushing-tanks it when the trip-buckets are employed instead of the siphons, as has been heretofore described, will take place as follows: Assuming the tanks to be filled with water, as indicated in Figs. 8 and 10, water will commence to flow from the supply-cock n during a flushing interval into the trip-bucket 12. When the weight of the water in the trip-bucket is suflioient, it will cause the bucket to descend and the trip-beam to be actuated to open the outlet of the tank, and the contents thereof will be discharged. In the case of the siphondischarge the trip-beam, returns at once to its original position, thereby insuring the immediate filling of the tank as soon as a complete discharge has been eflected. In case of the valve-discharge, as soon as the float has de-- scended, it will cause'the bell-crank levern to'become disengaged from the pin n whereby the trip-beam will return to its original position and the tank will be filled.; Finally, the water in the trip-bucket having been partially or wholly discharged through the opening in the bottom thereof, said bucket will return to its original position, being in readiness to effect the actuation of the trip-beam at the next flushing interval. The tanks 91, maybe filledin the first instance by opening the supply-cock n to its full extent or in any other suitable manner.

In order to provide against any serious consequences which might be occasioned by the clogging of the main' sewer or any of the waste-pipes,a safety device (see especially Fig. 7) is provided and may be attached to any and all faucets or discharge-openings in the system. Said safety device comprises a float 6, having an arm {a secured thereto, which arm is loosely fitted in a bearing o. This safety device is mounted with respect to a discharge-opening or faucet in such away that the float will rest normally in the bowl or tank into which said faucet discharges, while the rod mounted upon said float will be in a vertical line with the opening in said faucet. The upper end of said rod is provided with a plug or stop-ball w, which upon the upward movement of said rod is adapted to be jammed into the opening of aperforated plug 0, which, as before described, is provided upon each of the faucets, said opening being float in said tank, (see Fig. 3,) whereby whenthe closet becomes clogged the last-mentioned rod will be raised and the supply-cock for the flushing-tank will be closed.

I claim as my invention 1. The combination with a water-supply pipe provided with a valve to control the flow therethrough, of a tank, a pipe leading from the supply-pipe to the tank and also controlled from said valve, means controlled by the rise and fall of water in the tank to close and open the valve and thereby permit a flow through both of said pipes when the tank is empty, and shut off the flow through both when the tank is filled, and means for discharging the contents of the tank.

2. The combination with a water-supply pipe provided with a valve to control the flow therethrough, of a tank provided with means for dischargingits contents, a float in the tank, connected with the valve and adapted when raised to close the said Valve and when lowered to open it, and a pipe connected to the supply-pipe beyond its valve, and opening into it. i

3. The combination with a water-supply pipe provided with a valve to control the flow thercthrough, of a tank, afloat in the tank connected to the valve to close it when raised and open it when lowered, and a branch pipe leading from the supplypipe beyond said valve and discharging into the tank; said tank having an outlet of less area than the said branch pipe to permit the tank to be filled and slowly emptied.

4. The combination with a water-supply pipe leading to a part to be flushed and there terminating in a perforated plug, a valve in the pipe to control the flow therethrough, of a tank, a pipe leading from the supply-pipe to the tank and controlled from said valve,

means controlled by the rise and fall of the water in the tank to close and open the valve.

5. The combination with a water-supply system in a building or dwelling, which system comprises a water-main and service-pipes leading to different parts of said building or dwelling and having their ends open for the passage of water therethrough, of a valve in said main controlling the flow of water through said main, a tank in the upper part of the building or dwelling provided with supply and-discharge pipes and adapted to receive a supply of water when said valve is open, means controlled by the water in the tank for opening and closing said valve, a pipe leading from the discharge of said tank to said servicepipes', a valve in said pipe, a second tank in the lower part of said building or dwelling provided with supply and discharge pipes and adapted to receive a supply of water when said second-named valve is opened, and means controlled by the water in said second-named tank for opening and closing said secondnamed valve.
